Septentrio timing GNSS module supports Fugro AtomiChron

The mosaic-T module already includes several layers of security against GNSS jamming and spoofing with AIM+ integrated technology and OSNMA Galileo authentication. AtomiChron further strengthens the anti-spoofing security of the mosaic-T receiver by offering Navigation Message Authentication (NMA) on all 4 major GNSS constellations.

Numerous sectors rely on resilient and highly accurate time synchronisation, including finance, data centres, energy, and telecommunications. Fugro AtomiChron includes NMA, which ensures timing resilience through the reception of only genuine GNSS signals. The need for high accuracy is answered by eliminating time drift caused by clocks counting time at slightly different rates. This achieves Sub-nanosecond accuracy and provides extreme stability that surpasses current precision frequency standards. This is a lightweight and scalable solution, which removes the need for atomic clocks in critical infrastructure.

“Adding the Fugro AtomiChron service to the mosaic-T will allow for numerous new GNSS-based timing applications, from enabling increased resilience for timing in critical infrastructure markets to providing the highest timing accuracy for cutting-edge research applications such as quantum computing. This technology raises the bar for the whole time and frequency industry”, stated Roel de Vries, Business Development Manager for AtomiChron at Fugro.

“We are excited to offer the next level of resilience for mission-critical infrastructure, with the mosaic-T timing receiver. AtomiChron service further enhances mosaic-T’s timing precision and anti-spoofing capabilities with its advanced four-constellation authentication,” explained François Freulon, Head of Product Management at Septentrio.

The mosaic-T delivers accurate timing with multi-frequency, multi-constellation GNSS technology and offers dedicated timing features and inputs for time and clock synchronisation. AtomiChron capability can be obtained via a software upgrade for new receivers or for receivers which are already operational in the field. The AtomiChron service is optional and can be activated through Fugro.
